“I cannot ignore those laws any more than I can ignore any of the other laws that are on the books,” Obama said. “That’s why it’s important to get comprehensive immigration reform done this year.”

Support for that view among reform advocates is splintering, a fact becoming clearer by the day. The president of the National Council of La Raza, the country’s largest Latino advocacy organization, this week coined the “deporter in chief” term for the Democratic president the group has worked with in the past.

Then Rep. Luis Gutierrez, Obama’s fellow Illinois Democrat, used the same phrase on the House floor as he complained about Obama’s policy of continuing to deport illegal residents.

When Obama sat down for a town hall meeting Thursday, hoping to boost Latino enrollment in health insurance plans, one of the Spanish-speaking hosts started off by asking about the “deporter in chief” comment.

Obama answered that he has been pushing for comprehensive reform.

“I am the champion in chief of comprehensive immigration reform,” Obama said. He pointed out that his administration has turned its focus away from deporting young immigrants brought to this country when they were children and instead put the priority on immigrants in the country illegally who are involved in criminal or gang activity.

But in so doing, he said, he has already stretched his administrative capacity.

“At a certain point,” he said, he has to enforce the laws on the books even while pushing to change them.

Reform advocates think otherwise. Gutierrez has harshly criticized the GOP for blocking change in the laws but argues that while Obama seeks such change he can carry out a fairer policy using his executive power.

"Republicans can either be participants in how this country advances more sensible immigration policies or they can simply sit on the sidelines while the president does it with his phone and pen,” Gutierrez said this week.

Obama remained resistant to that idea Thursday. In the town hall session, he said he has spoken with Speaker John A. Boehner (R-Ohio) about trying to resurrect immigration reform this year even though the initiative has hit a roadblock in the House.

Amid heightened speculation about whether he will seek the Democratic presidential nomination, Vice President Joe Biden remains at least a month from a decision and has largely left preparatory work to a small circle of trusted longtime aides.
